This feature is known as truncate optimization. SQLite will delete all rows in one shot instead of visiting and deleting each individual row. Notice that when you use the DELETE statement without a WHERE clause on a table that has no triggers. The ORDER BY clause sorts the rows filtered by the preceding search_condition in the WHERE clause and the LIMIT clause specifies the number of rows that to be deleted. LIMIT row_count OFFSET offset Code language: SQL (Structured Query Language) ( sql ) If you compile SQLite with the SQLITE_ENABLE_UPDATE_DELETE_LIMIT compile-time option, you can use the ORDER BY and LIMIT clause in the DELETE statement like the following form: DELETE FROM table WHERE search_condition SQLite also provides an extension to the DELETE statement by adding ORDER BY and LIMIT clauses. ![]() If you omit the WHERE clause, the DELETE statement will delete all rows in the table. The WHERE clause is an optional part of the DELETE statement.
